   <h3>Via data attributes</h3>
   <p>Use data attributes to easily control the position of the carousel. <code>data-slide</code> accepts the keywords <code>prev</code> or <code>next</code>, which alters the slide position relative to its current position. Alternatively, use <code>data-slide-to</code> to pass a raw slide index to the carousel <code>data-slide-to="2"</code>, which shifts the slide position to a particular index beginning with <code>0</code>.</p>
